Transmitting apparatus, receiving apparatus, transmitting method, and receiving method

摘要

There is disclosed a radio transmission device capable of improving the throughput. The radio transmission device transmits a first signal and a second signal which are different from each other. In the radio transmission device, an FFT unit subjects first data to an FFT process. A sub-carrier allocation unit maps the first data which has been subjected to the FFT process and the second data into different frequencies. An IFFT unit subjects the mapped signal to the IFFT transform. A transmission radio processing unit transmits the signal which has been subjected to the IFFT processing, with a single carrier.
